Oxidant-Free Atomic Layer Deposition of SnO2 Using Complementary Metal Precursors

Alejandra Ruiz‐Clavijo, Amin Bahrami, Jonathan E. Rodriguez Hueso, Jaakko Julin et autres

We report a novel atomic layer deposition (ALD) process for SnO2 that does not require water or other strong oxidizing agents, such as H2O, O2 plasma, O3, or H2O2. The development of alternative oxidant-free ALD processes is highly attractive because it enables …

Enhanced Growth in Sb2Te3/SnSe2 Multilayered Atomic Layer Deposition: Nucleation and Nanostructure Modification

Dong-Ho Shin, Amin Bahrami, Philipp Brüner, Ji Liu et autres

Abstract Multilayer thin film structuring offers a versatile strategy to tailor nanostructures through interface engineering. Atomic layer deposition (ALD) provides precise control of composition and structure via supercycle approaches that enable the multiple metal species introduction. However, the resulting growth behavior is …

Proton‐Switching Regulates Interfacial Iodine Chemistry for Long‐Life Zinc–Iodine Batteries

Feifei Wang, Guoqin Liu, Yuhang Zhuang, Peng Zhang et autres

ABSTRACT Aqueous zinc–iodine (Zn–I 2 ) batteries are promising candidates for safe and cost‐effective energy storage, yet their practical application is limited by uncontrolled iodine speciation at electrified interfaces, driving severe polyiodide shuttling and parasitic reactions that cause rapid capacity fading. Existing …

Spontaneous symmetry breaking enables anti-rolling motion of MnO2 microrods

Martin Wittmann, Marco De Corato, Shivam Singh, Yana Vaynzof et autres

Spontaneous symmetry breaking in colloidal systems increasingly fascinates scientists due to the promise of new, emergent functionalities and unique properties. Here, we introduce a chemically active system where symmetry is spontaneously broken in the particle motion rather than being encoded into their …

Charge Transport in All‐Inorganic CuInSe 2 Nanocrystal Transistors: Linking Material Design and Device Performance

Nadia Günther, Borja Rodriguez‐Barea, Jasmin L. Herzog, Bjarne E. Stern et autres

ABSTRACT Solution‐processable semiconductor nanocrystals (NCs) offer a versatile, highly tunable platform for low‐cost, next‐generation electronics. However, their integration into field‐effect transistors (FETs) remains limited by the challenge of optimizing synthesis, surface chemistry, and charge transport. In this work, CuInSe 2 NCs are …
